Saturday, second baseman Dustin Pedroia and reliever Alfredo Aceves got into a shouting match in the Red Sox dugout in the top of the fifth of a game Boston eventually lost to the Oakland A's, 7-1. Third base coach Jerry Royster separated them. (See video)

Manager Bobby Valentine said the conversation between the two teammates was about "positioning" of the team's infielders. Pedroia said the exchange would remain private.

"That's none of your guys' business," Pedroia said after the game, according to WEEI.com. "That's between teammates."

Aceves said: "It was something that we have to communicate on, between us, but that’s us. That stays with us. That’s part of the game. Whatever happens in the game stays in the game."
